PATENT OEEIcEc WILLIAM c. oooK, OF. JERSEY OITY HEIGHTS, AssIeNoR TosYLvANUs sEY, AND'ANsON R. HOYT, OE YONK- IMPROVEMENT IN SASH-FASTENERS.

i Specification forming part of Letters Patent No. 174,489, dated March7, 1876; application filed November 1o, 1815.

To all whom it may concern:

Be it known that I, WILLIAM G. COOK, of

'-Jersey Uity Heights, in the county of Hudof the same, reference beinghad to the accom panyin'g drawing, which forms part of thisspecification.

This invention relates to gravitating sash fastenings or holders pivotedto the sash, and locking with or between stops on the windowframe.

The invention consists in a combination of a pivoted gravitating doublecatch having reverse notches on its opposite ends, a catchholdercarrying the same and attached tothe sash, and a series `ot'irregularly-arranged stops on the window -framet'or arresting either endof the catch to hold the sash up or down and closed or open, asrequired.

Figure 1 represents aavindow-frame having upperand lower sashes, with myimprovelnent applied to the ylower sash. Fig. 2 is a vertical section ina plane at right angles to the window, with the lower sash as stoppedand locked 'by my improved device in difterent positions. Fig. 3 is aside view, and Fig. 4 a horizontal section in part, both upon a largerscale, of a Window-sash having my improved sash-i'astener applied.

A is the window-frame, having a raising and lowering bottom sash, and anupper sash. Secured to the face of the lower sash, on its one side, is asash-catch carrier, D. This carrierserves to support in a swingingmanner, as by a pivot, b, a double catch, G, having said pivot, whichmay either be fast to the catchor not, arranged intermediately of thelength of it. Such double catch is supported by the carrier D, so thatit is restricted by a back rest, c, from swinging but slightly from anupright position, Aand it is furthermore provided with a handle, d,which opera-tes also' as a weight to pitch and hold the catch in astopping and locking position with studs or stops g on the window-frame.

The two ends of the double catch are notched or'cut away, as at e e,which notches are in a reverse relation with-each other, and the stops gon the window-frame are arranged out'of line with one another, or, wheremore than two of such. stops are used, so that the lower series of saidstops will be out ot' line with theupper series thereof, in. order thatthe reverse notched Vends ot' the catch will lock, respectively, withthe stops to 1hold the sash open or closed, or in anylintermediateposition, according to the number and disposition of the stops.

In Fig. 2 of the drawing the lower sash is represented, lin full lines,as locked when closed by the upper notched end of the double catchfalling under one of the stops g, and is, `fnrther represented in dottedlines as locked when partly 4open or raised by the lower notched end ofthe double catch falling over another of the stops g. .t

The stops with which the lower notched endV of the double catch-lock arearranged closer to the sash than those 'stops with which the upper-notched arms ot' the catch,l for the double purpose 'of insuring theautomatic locking of the reverse ends of the double catch, by means ofits weight or handle d, with said stops, respectively, and ot' allowingthe catch C, when lit'ted by the handle into an upright position,passingin front of the one stop or series ot' stops g, and behind theother, when moving the sash B up or down. On removing the linger,however, from the finger-piece or handle d, the latter innuediatelydrops, and thc catch is adjusted into an inclined position, and is freeto swing away from any stop g it may come in contact with by the frontface of its upper arm, or back ot' its lower arm, according to thedirection inwhich the sash is being moved, and so that, after said catchhas thus passed or rubbed over and swung away from said stop, its.weight or handle d will automatically throw it into lock with saidstop.

I claim'- The combination of the pivoted gravitating double catch C,having opposite end notches .e e, arranged in reverse relation to eachother,

the catch-carrier D attached to the sash, and the stops g on thewindow-frame, arranged out of vertical line with each other,substantially as shown and described.-
